Well, they couldn't figure out the measuring tape
By "they" do you mean all Polish builders or these particular men who worked with your brother once?. I presume they worked for your brother once because nobody would continue work with such cowboys.
A difference should be made clear.
I cringe every time i hear the word "THEY" or "THEM".
I have worked on many jobsites where we had to go back and correct mistakes.
I have worked with unskilled men from many countries who pretended they were trades men ha ha ha.
I would just like to point out one horrible thing that happens to many immigrants.
Forced immigration due to financial reasons need to work as soon as possible and do lie about their abilities.
Outside Victoria station in London there are gangs of Polish people waiting each morning for the chance to obtain work.
A van will pull up and ask "who here is a plumber, carpenter, painter etc.?" everyone will raise their hand because they are desperate.
This is an illegal practise.
I am led to believe something similar in the U.S happens with Mexicans.
There are many horror stories connected to these people who have fallen on hard times or perhaps have never known a good time.
I speak from an Irish perspective, it was very similar for us in London.
In some ways better because of the language and in other ways worse because of the war.
It would break your heart what goes on.
I think I am a bit serious on here these days, hmmm.
